CO-35: Lifetime Benefit Maximum Reached

What Does CO-35 Mean?

With CO (Contractual Obligation), the CARC 35 adjustment for lifetime benefit maximum reached is a contractual reduction. The provider absorbs this amount per the payer contract or regulatory payment methodology. The patient is not responsible for the adjusted amount. Review the remittance to confirm the adjustment is consistent with your contract terms.

CARC 35 indicates lifetime benefit maximum reached. The payer determined that the service or a portion of it does not meet coverage criteria under the patient's current plan benefits or the applicable coverage rules.

Common scenarios that trigger this adjustment include: patient has reached the lifetime dollar limit for covered benefits under their plan; Patient has used the maximum number of allowed visits or services for a particular benefit; Pre-ACA grandfathered plans may still have lifetime dollar limits. The group code paired with CARC 35 determines who bears the financial responsibility — CO places it on the provider as a contractual obligation, PR shifts it to the patient, OA indicates a coordination of benefits or other payer adjustment.

Common Causes

How to Resolve

1. Review the adjustment against contract terms Compare the CO-35 adjustment with your payer contract to confirm the reduction is consistent with agreed terms or regulatory methodology.
2. Verify the adjustment amount Confirm the dollar amount of the adjustment is calculated correctly based on the contracted rate and the service provided.
3. Appeal if the adjustment is incorrect Under the ACA, most health plans cannot impose lifetime dollar limits on essential health benefits. If this is a non-grandfathered plan, appeal citing ACA Section 2711. If the lifetime maximum count or amount is incorrect, appeal with benefit usage records.
4. Process the contractual adjustment If the adjustment is correct per contract terms, process it accordingly in your billing system. This amount cannot be transferred to the patient.
